84 THE CANADIAN ENTOMOLOGIST. 



the Pawpaw, Asimina; P. Philoior, species of Aristolochia (though, 

 according to Scudder, Polygonuvi convolvulus, or knot Bindweed). On 

 the other hand, some species are ahiiost omnivorous, as P. Turnus, which 

 is credited with eating plants in a score of genera. P. Asterias, and its 

 alhes, Brevicatida, Machaon, etc., feed exclusively on Umbelliferge, car- 

 rots, fennel, parsley, etc. The Pieridae feed on Cruciferae, cabbage, tur- 

 nip, radish, horse-radish. The Coliadse on clover, pea, lupine, astragalus. 

 Callidryas and Terias on Cassia. Danais on Asclepias. Argynnis on 

 Violet, though A. Idalia also on a species of Aster. The Graptas on 

 nettle, elm, hackberry (Celtis), currant, gooseberry, false nettle (Boeh- 

 meria) ; Apatura on Celtis ; Limenitis on willow, hawthorn, aspen and 

 poplars. 



Our species of Lyceena, so far as known, on a variety of flowers, as 

 Pseudargiolus, in its several forms, on dogwood, rattle-weed (Cimicifuga) 

 and Actinomeris ; Scudderii on lupine and on Jersey tea (Ceanothus). 

 Co my nt as on clover, blossoms and leaves. Melissa on Astragalus. Thecla 

 larvae I know very little about, the only one I ever saw being that of 

 Henrici, which feeds on the inside of plums, jyild plums, excavating the 

 whole interior of the fruit. But many species are said to feed on leaves 

 of oak : Melinus on hop, thorn, etc., F. Tarqulnius on hawthorn. The 

 Satyrids all feed on grasses and sedges. So Pamphila feeds on grasses 

 and sedges ; Nisoniades on herbaceous plants and shrubs. 



Wherever I have lived in the country, as at Newburgh, New York, for 

 several years, and later, at Coalburgh, W. Va., I have brought into my 

 grounds all trees, shrubs and plants, on which larvae of butterflies are 

 known to feed, so far as I could get them. So that I am pretty certain to 

 have food of almost any species close at hand. Thus, in addition to 

 plants from the region around Coalburgh, I have Astragalus, Amorpha 

 and Scrophularia from California, aspens from the Catskill Mountains, and 

 even a particular nettle from the north, for V. Milbertii, which I found 

 last year starved to death on our native nettles, Milberiii being an exotic 

 species here. 



Now, the plant supposed to be known, we wish to get eggs of butter- 

 flies laid on it. If a tree or shrub, I use a bag or bags of Swiss muslin, 

 but mosquito netting often, especially for large butterflies, as Papilios. 

 For Papihos, the bag is about 30 x i8 inches. For medium sized species, 

 as Graptas, say 18x10; for Lycaenae, 10x6, having always on hand 

 several sizes. If there is any reason for keeping a particular female
